Ni80 Ni90 Nichrome Heating Wire Nickel Chrome Wire For Electric Heating

Ni80 NI90 Nichrome Heating Resistance Nickel Chrome Wire For Electric Heating

Features:

• High Electrical Resistivity
• Excellent Oxidation Resistance
• Low Temperature Coefficient of Resistance
• Annealed Soft Temper
• Ultra fine diameter

Description:

Our nickel‑chromium resistance alloy micro wires are engineered for high‑temperature heating elements and precision resistors. The family includes six standard grades, each optimized for different operating temperatures and resistivity requirements. Common characteristics include excellent oxidation resistance (thanks to a protective Cr₂O₃ layer), stable electrical properties over a wide temperature range, and good mechanical strength even after prolonged thermal cycling.

Specifications:

Applications:

• Heating Elements: Electric furnaces, industrial ovens, heat treatment equipment, kilns, and cartridge heaters.
• Household Appliances: Toasters, hair dryers, electric irons, water heaters, and rice cookers.
• Electronics: Wire‑wound resistors, rheostats, load banks, and precision potentiometers.
• Aerospace & Defense: De‑icing systems, high‑temperature sensor leads, and engine ignition components.
• Laboratory Equipment: Muffle furnaces, tube furnaces, heating mantles, and thermal analyzers.
• Automotive: Glow plugs, heated mirrors, seat heaters, and exhaust gas sensors.

FAQ

Q1: Which grade should I choose for my application?

A: For maximum operating temperature up to 1300°C, choose Cr10Ni90. For general heating elements up to 1200°C, Cr20Ni80 is the industry standard. For cost sensitive projects with lower temperature requirements (≤1100°C), consider Cr20Ni35 or Cr20Ni30.

Q2: Can I get a sample before bulk order?

A: Yes, free samples of any grade are available upon request if in stock. You only pay shipping.

Q3: What is the lead time?

A: Samples ready in 2–3 days. Mass production takes 7–20 working days depending on quantity and grade.

Q4: Is there a minimum order quantity (MOQ)?

A: MOQ is 5 kgs.

Q5: How do you prevent the wire from tangling during shipping?

A: We wind on anti static plastic spools and seal in protective boxes. Each spool is inspected under magnification.

Q6: Do you offer a warranty?

A: Yes, 12 month warranty against manufacturing defects. Mill Test Reports (MTRs) are available with full batch traceability.

Q7: How to handle faulty wire?

A: Defect rate below 0.5%. During warranty, we replace faulty length on your next order or respool a new coil at no cost.
